Enum DnsServerWatcherRequest

Source

pub enum DnsServerWatcherRequest {
    WatchServers {
        responder: DnsServerWatcherWatchServersResponder,
    },
}

Expand description

Provides a hanging get interface to watch for DNS servers configuration.

Variants§

§

WatchServers

Returns a list of DNS servers.

First call always returns a snapshot of the current list of servers or blocks if an empty list would be returned. Subsequent calls will block until the list of servers changes.

The list of servers changes over time by configuration or network topology changes, expiration, etc. Callers must repeatedly call WatchServers and replace any previously returned servers with new ones to avoid using stale or expired entries.

It is invalid to call this method while a previous call is pending. Doing so will cause the server end of the protocol to be closed.

response servers The list of servers to use for DNS resolution, in priority order.
